|Textile Properties of an Innovative Textile for Low-Strain Sports|
|Martin Harnisch, Bekleidungsphysiologisches Institut Hohenstein, DE
Natural fibres are said to be more comfortable in every day life without high physical strain. On the other hand man made fibres are said to be more suitable for sports clothing with high activity and temperature. To combine benefits of both fibre types double-face and denier-gradient textiles were developed. Double-face textiles have man made fibres on the inside and hygroscopic natural fibres on the outside. Denier-gradient textiles use yarns with differing titre. Both constructions offer very good thermophysiological properties. But their production is complicated and therefore relatively expensive. That’s why they are not used for casual wear or fashionable clothing. A research project was started to combine both fibre types in one yarn. Man made fibres are spun around natural ones. In the end it will be possible to have a one layer textile with thermophysiological properties like denier-gradient or double-face and is easy to manufacture simultaneously.
|Factors Influencing Thermophysiological Wear Comfort of Sports Clothing|
|Alexandra De Raeve, HoGent, BE
Sports clothing has a number of functions: establish identity, adornment, protection and allow to perform.
As homoiothermic being man is challenged to maintain its body temperature between 36,5 and 37,5 °C. This contrasts sharply with the ambient temperature which may vary widely. Solar radiation, humidity, wind and precipitation can create even more extreme thermal conditions.
|New Software for Thermal Comfort Sensation|
|Cyril Chaigneau, Damart Sport, FR
DAMART SPORT was created in 2007 as a part of DAMART’s answer to new seniors.
53% of over 50 years old people are doing sport ( cycling, walking, swimming) which is representing 10 million people. To be able to answer as precisely as possible to them and to create the good product for the good activity in a given environment, Damart decided to create a brand new innovative software. Resulting of a 5 years R&D partnership between DAMART (55 years of knowledge in thermal comfort), INFLUTHERM (experts in thermal exchanges) and ENVEHO (experts in human physiology and textile), this software handles all thermal exchange between textile, body and environment. Thanks to the use of GAGGE thermophysiology model, it is possible to calculate skin temperature, wet skin percentage (but also fabric temperature for example) as affected by all thermal exchanges in correlation to the activity and textile properties. The dynamic mathematic model used and the given thermal sensation have been validated thanks to more than 300 hours of in-vivo tests and record of 950 curves of physiological parameters associated with well-being questionnaire recorded during sport activities of different intensity.
|Fabric Innovation for the ‘Sports Culture’|
|Alain Langerock, Devan, BE
Sports and Fashion have always been a successful formulation – looking good when on the field and also looking sporty in everyday life, has been important for many years. For the world’s major sports labels ‘sports culture’ products take up the largest share of their product ranges – their income depends on this continuing in the future.
This amalgamation of sporting and casual wear products will inevitably change or inspire new fabric innovation. Some of the new innovations will be related to textile construction and to garment technology, but we will see an increasing amount of innovation in this area based on chemical finishes. We can achieve subtle but important developments on fabrics using certain chemistries, for example; greater hydrophilicity (moisture management), greater hydrophobicity (water repellent), odour control, increased thermoregulation, and increased stretch recovery, to name a few. Devan’s presentation is designed to highlight the importance that chemical finishes have in fabric innovation, to this economically important area of sportswear.
|Heated Outdoor Clothing|
|Lieven Tack, Bekintex, BE
Everyone is keen on having a heated jacket during winter time, but integrating wires into textiles to generate this heating, is complex and labour intensive. To answer this question, Bekaert, as producer of the Bekintex stainless steel heating wires and yarns, has developed a new, robust and user-friendly product based on car seat heating technology. The technique Bekaert uses to do this, allows integrating heating wires easily in the form of machine washable textile pads. These pads can be sewn directly onto the jacket liner to be close to your body. Connected to a small battery pack or standard adaptor, the heating element will generate an equally distributed heating, which increases comfort and safety for people working in cold environments. Depending on the requested temperature, the heated surface and the size of the battery, the heating can last from several hours to almost one day. Each pad is engineered in such a way that it will produce a specific amount of heat. The special production technique is flexible and allows producing almost every size or shape. One can imagine that such a flexible product can be used in a variety of textile products. Imagine heated leisure and sportswear, heated industrial wear, military clothing, heated clothing for elderly people, heated clothing for disabled people, etc. Bekaert also helps garment producers to design the right heating pad and informs them on how to connect and which batteries to use.
